Review Case Reports
Rasmussen encephalitis with dual pathology in a patient without seizures: case report and literature review.
Rasmussen encephalitis without seizures is rare. We report a case of Rasmussen encephalitis and cortical dysplasia without epilepsy as well as describe the imaging, pathology, and clinical course and review the literature to investigate whether this may represent a rare subset of Rasmussen encephalitis. ⋯ To the best of our knowledge, this is the third case of Rasmussen encephalitis diagnosed by both imaging and histopathology that had no clinical or electroencephalographic evidence of seizures and is the only case of Rasmussen encephalitis with cortical dysplasia without epilepsy.

Hemispherectomy and disconnective hemispherotomy are the most effective epilepsy surgical procedures for the treatment of epilepsy due to hemispheric pathologies such as Sturge-Weber syndrome, diffuse hemispheric cortical dysplasia, and posttraumatic and postischemic focal lesions. Disconnective hemispherotomy is nowadays preferred to reduce surgical morbidity in term of early and late complications (i.e., cerebral superficial hemosiderosis). Despite the number of existing technical variants conceived to further reduce the amount of brain tissue to be removed, postoperative hydrocephalus still persists and may account for an average incidence of 15-41% according to different series and reviews. A new variant of disconnective vertical hemispherotomy we termed vertical extraventricular parasagittal hemispherotomy is described aiming to further reduce the amount of removed brain tissue and so the risk of postoperative hydrocephalus in favor of a pure hemispheric disconnection. ⋯ Vertical extraventricular parasagittal hemispherotomy may be an efficacious and less invasive technique as it consists in a pure disconnection of the hemisphere with less amount of brain tissue removed and a theoretical reduced risk of postoperative hydrocephalus.

Despite pediatric guidelines, variability exists in the management of severe traumatic brain injury (TBI), as somewhere between 7 and 60% of children undergo intracranial pressure (ICP) monitoring. Reasons for this low adherence to TBI management guidelines remain unclear. The objective of this study was to evaluate the current practices at CHU Sainte-Justine with regards to ICP monitoring in severe TBI and explore the reasons why ICP monitoring is not undertaken. ⋯ Our study confirms that many children with severe TBI do not undergo ICP monitoring, mainly due to rapid improvement or moribund status. A subgroup of patients, with reassuring cerebral CT scan, was not monitored. Further research is necessary to assess if imaging should be considered in ICP indication, as in adult guidelines.
